Draytek Vigor 2820Vn ADSL2/2+ Security Firewall Wireless 802.11n

Draytek Vigor2820Vn Dual WAN ADSL 2/2+ Modem/Router Security Firewall with VoIP

The Draytek Vigor2820Vn is an ADSL2+ IEEE802.11n Compliant ( Draft 2.0 ) Modem Router Security Firewall device with a 2nd Ethernet WAN port (Dual WAN). This 2nd WAN can connect to DSL/Cable modem or fiber media converter for policy-based load-balancing, fail-over and Band Width on Demand (BoD); it also features advanced bandwidth control mechanisms such as IP-layer QoS, NAT Session Limitation, Bandwidth Borrowed, etc., to provides you with easy, flexible and reliable access control and bandwidth management.

The SPI (Statefull Packet Inspection) firewall uses Object-Based design to make setting of the firewall policies a snap! The CSM (Content Security Management) feature allows more precise and efficient access control for URL/Web Content Filtering, IM (Instant Messenger) and P2P (Peer-to-Peer) applications.

Wireless Application
Vigor2820Vn model complies with 802.11n ( Draft 2.0 ) standards. Supporting WEP / WPA / WPA2, encryption and MAC Address Control, Wireless LAN Isolation, Multi SSID and 802.1x authentication. The Wireless Rate Control function can adjust the data rate of each wireless station ( client ). WDS can help users to easily extend wireless coverage.

 

VPN Firewall Application
With the hardware-based implementation of the VPN protocol, the Vigor 2820Vn supports up to 32 VPN tunnels using advanced protocols such as IPSec/PPTP/L2TP over IPSec with AES/DES/2DES for encryption and MD5/SHA-1 for authentication.

The SPI firewall uses Object-Based design to make setting of firewall policies easy. The CSM feature allows more precise and efficient access control for URL / Web Content Filtering, IM and P2P applications.

 

VoIP Application
Vigor2820Vn models provide twin analogue phone and one line port. It supports multiple SIP Registrars with high flexible configuration and call handing options.

Benefits of Digit-Map for FXS port and Line Port

You can connect your regular analog line (PSTN/POTS*) to the Line port of Vigor2820Vn. While you enable VoIP facility, you still can access fixed line (analog line) to make calls just by dialing #0. The phone connected to Line port and FXS port can be used for both POTS calls and VoIP because the incoming calls are automatically switched through to your telephone(s) (either one or both).

As a result, both analog telephones plugged into your router allow you to access VoIP and analog lines. Furthermore, you can set rules through "Digit-Map" function about particular call destinations using either your SIP/VoIP service or the POTS line. e.g. you can route local calls via your PSTN line (if you have a free calls package) whereas international calls can go via your preferred VoIP provider; there is flexibility to have several digitmap rules. The implementation of Digit-Map facilitates the VoIP calls with SIP accounts as well as offering "Least Cost Routing" functionality.

 

CSM / 3.5G Fail-over Backup
Vigor2820 series CSM (Content Security Management) function can block selected P2P and instant message applications. This would not only help employees stay focused on their job but also prevent possible treats from those applications damaging corporate essential data severs.

3.5G fail-over backup can keep business continuous during downtime of the leased line from ISP.
